     Also, an apparatus provided with a peg unit (40) having the above two pegs (35, 36) together with mechanism  (60) for changing the axial distance between these two pegs. Th         e apparatus is further provided with an additional mechanism (70) for displacing the peg unit to desired positions to carry out the unit operation for exchanging roving bobbins, and a mechanism (90) for displacing the apparatus along the spinning frame to carry out the successive unit operations for exchanging roving bobbins from one side-end to the other of the spinning frame.

Abstract: A drive device, consisting of a drive motor (1), whose speed can be varied by an operating member, an adjustable hydrostatic transmission (26) with a pump (3) and a hydraulic motor (5) having a variable supply and/or scavenge volume, a multiple gear transmission (7), which is connected downstream of the hydrostatic transmission (26) and whose gear can be changed particularly under load, a control device (20) being allocated to the hydrostatic transmission (26), and an operating element (9) to initiate a gear change being provided, is to be designed such that, while ensuring a simple control concept, a subjectively good gear-change response is produced, even without costly additional devices having to be used in the control response of the continuously variable hydrostatic transmission (26). This is achieved by a device (13, 14) which confirms the transmission direction of the power transmitted between the drive motor (1) and the multiple gear transmission (7) being allocated to the control device (20), by the control device (20) adjusting the transmission ratio of the hydrostatic transmission (26) in the direction of reducing the output drive speed of the hydraulic motor (5) after the initiation of a gear change into a lower gear (I), when power is being transmitted from the multiple gear transmission (7) to the drive motor (1), and by the gear change process taking place at the earliest when reaching the situation that power is transmitted from the drive motor (1) to the multiple gear transmission (7).

Abstract: An electronic blackboard wherein a multiplicity of heads for reading and writing storage data in relation to memories are disposed lengthwise and breadthwise on the surface of a board so that data can be read from and written into the memories on the board surface. Also disclosed is an electronic blackboard system which comprises input/output control means for controlling a storage data input/output operation in which heads which are disposed on the surface of a board are sequentially scanned to read or write storage data and data processing means for processing storage data, whereby storage data relative to a memory which is stuck on the board surface is read or written with a predetermined relationship between the head position and the storage data. 
     By virtue of the above described arrangement, when a memory is stuck on the board surface, storage data is read from or written into the memory by means of the corresponding head through the input/output control means, and the read/write data is processed in the data processing means. Accordingly, it is possible to store data into memories on the board, read the data from the memories, and process data corresponding to the position of each memory stuck to the board surface.

Abstract: In a noise eliminating apparatus including a recursive filter (8A) having a delay circuit (1-6) to delay a video signal by only a predetermined period of time, each of recursive coefficients of a plurality of spatial frequency components included in the difference signal between the input video signal and the delayed video signal is changed in accordance with a movement detection output based on the difference signal. Thus, the dimming due to the motion of an image can be reduced to such a level that no visual problem occurs and the high frequency noises are also eliminated because of the correlation between the frames. Therefore the dimming phenomenon due to the motion of the image in the moving portion can be reduced and the sufficient noise eliminating effect can be obtained.

Abstract: The improved high pressure oxygen-saturated water treatment apparatus (10) of the present invention functions to provide super-saturated oxygen treatment to waste water for purification thereof. The apparatus includes a pressurized treatment tank (12) having a substantial longitudinal dimension, with a chamber separation plate (14) forming two interconnected chambers (16, 18) in the tank (12). An input conduit for flowing waste water into the first chamber of the tank is provided. An oxygen input conduit (22) is connected to the tank for providing oxygen-containing gas under substantial pressure within the tank. An oxygen output conduit (30) is also disposed on the tank (12) for receiving the oxygen-containing gas from the tank to form a pressurized oxygen-containing stream. A venturi (34) is also disposed on the tank for receiving and combining the pressurized oxygen-containing stream with recirculated water from the tank to form a combined injection stream (36) of pressurized water which is super-saturated with oxygen, and which is then injected into the treatement water contained within the tank. As the tank is maintained at a pressure lower than that of the injection stream, the pressurized oxygen comes out of solution in tiny bubbles preferentially about particles of solid waste to entrain and provide supplemental floatation thereto. The result is to substantially oxidize any oxidizable material contained within the tank. The treated water is then removed by suitable means from the tank from the second chamber thereof.
